APP: Losant Arduino MQTT Client Stack Buffer Overflow
This signature detects attempts to exploit a known vulnerability against Losant Arduino MQTT Client. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the current process.
Extended Description
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Losant Arduino MQTT Client prior to V2.7. User interaction is not required to exploit this vulnerability. The specific flaw exists within the parsing of MQTT PUBLISH packets. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-6436.
